Eventually if all goes well.
Is there arguably an 'individual' status we may assign (or individuals, in the case of identical twins or more arising from the first cell of fecundation) to the conceptus?
They are an individual you don't "assign" them that status.
Is that individual life adapted (in form and function) for existence and survival as per its environment at that age?
Obviously not if they are a baby. Can we reasonably expect the conceptus to continue surviving if the requisite environmental conditions continue unabated at that age/functioning capacity?
Hmmmmm. Is this the same question? Does any other living species exit the womb (as per the continuum argument having human concetion at the beginning) of the human female?
Not normally but thats the process of cloning so far. Eventually it will be done in vitro.
Finally, does the conceptus, as it develops from single cell through zygote and then embryo age, create its own capsule that protects it from tissue rejection by the host's life supporting body ... does the conceptus function to survive, whether willfully (as in dicision making) or otherwise?
Huh?
You asserted, superstitiously, "Eventually, if all goes well." If you're going to convince us that your superstition is superior to science, you'll have to do better than that, you'll have to pin-point the moment that the life conceived by the union of human gametes actually becomes human and tell us what species the life belonged to prior to your assumed starting point for human.
